A packaging and cooking device includes a bottom, top and four side walls, each including a first fold line parallel to and slightly distant from the bottom, a second fold line parallel to the first line, two opposing side walls including two diagonal fold lines in the portion of the side walls located above the first line, the top including two flaps, each having a free edge and connected to two opposing side walls and a hooking system enabling flaps to be held in closed position. The hooking system includes a tab connected to the free edge of a first flap and a cut-out, provided in a second flap for inserting the tab in an insertion direction, the cut-out extending in a direction approximately perpendicular to the insertion direction and including a projecting shape offset relative to the ends thereof and oriented in the direction opposite to the insertion direction.

A device for processing, in particular for ultrasound welding, of packaging sleeves and/or packagings includes at least two tools for processing, in particular for ultrasound welding, of packaging sleeves. Each tool has an operating region. The tools are supported in such a manner that there is produced between the operating regions a gap whose longitudinal direction corresponds to the transport direction of the packaging sleeves, and the tools are supported in such a manner that the size of the gap can be changed. In order also to enable continuous welding of the packaging sleeves in a reliable manner with changing material thicknesses, there is provided at least one parallel spring on which at least one of the tools is movably supported transversely relative to the transport direction of the packaging sleeves.

A device for cooking corn kernels for making popcorn comprising a non-folding volume and a folding volume. The folding volume is configured to take up at least two positions, a first position in which the folding volume is folded and a second position in which it is unfolded. The folding volume includes four walls and at least two walls include a diagonal fold. The device includes a top that delimits the folding volume in at least the second position. The top is formed by two flaps that are each secured to at least two side walls. The flaps are biased in the closed position and are opened by squeezing the vertical edges of the device together.

A composite includes a multilayer polyethylene terephthalate (PET) film having a base layer and an adjacent skin layer. The PET of the skin layer has inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T. The base layer can be affixed to a thin metal sheet. Optionally, the base layer of a second multilayer PET film with a skin layer inherent viscosity of about 0.70-0.90 and carboxyl endgroup concentration of less than 25 eq/T can be affixed to the opposite side of the metal sheet. The composite is suited for making food and chemical containers such as food storage cans that resist blush discoloration from steam contact during container formation and age degradation during extended storage of harsh chemical products.

The folding volume is configured to take up at least two positions, a first position in which the folding volume is folded and a second position in which it is unfolded. The folding volume includes four walls and at least two walls include a diagonal fold. Additionally, each wall includes a first horizontal fold that is parallel to an edge of the device formed by the non-folding volume. In the first position the non-folding volume is limited one or more of the four walls. At least one opening, in at least one of the side walls, has a horizontal orientation in the first position and a vertical orientation in the second position. The opening does not intersect a diagonal fold.
